Be it known that 1, JAMES W. CAIN, a

citizenof the United States, residing at De-' Unit, in the county of iVayne and State of Michigan, have invented a 'ne'w'and useful Spotlight Signal, of which the following is a specification.

This invention relates to signaling devices..-v

especially constructedfor use inaeonnectio I with motor vehicles, the primary; object 03? the. invention being rtoprovide a signal.

' I which may be clearl visih'le a the daylight to a mud guard.

- lamp.

35 4 connection between the lamp and its socket.

I 7 as well-as in the dark.

Another object of theinvention. is to provide a novel lamp construction to insure atrue-contactbetween the lamp and its socket,

to improve-the operation of thelamp.

With the foregoing and other objects 111 f view-' which. appear as the description proceeds, thei'invent-ion resides 1n-the c0mbination'and arrangement of parts, andin 1 the details (at-construction hereinafterdescribed and claimed, it being understood that changes within the scope of what 'is claimed, may be made without departing from the spirit of the invention.

Referring to the drawing 2+- Figure l is a sectional view through a lamp' forming apart ot-a signaling device constructed in accordance with the present inventlon, and show ngthe same as secured Figure 2' is a front elevational View of the at 5. A bracket: member indicated it-6' has connection with -the mud guard 5, as by means-of the bolts 7, it being understood however that the construction of the bracket may be changed to meet various requ1re-.

.The lamp casing embodies a circular'body portion 8 having a threaded portion 9 and a rear curved reflecting .wall' h1 0, 'the rear curved reflecting wall being formed with a threaded extension l1ter'minatingfin an inwardly extending circular flange 12. This circular flange 12 provides a seat for the in-.

sulating collar 13, which is held against'the flange 12 as by means oi the socket new drawing' a ean; the

14' that is also "formed with a threaded portion, as i drawing. 1

The socket member includes an inwardly extending threaded socket 15 designed to accommodate the lamp base 16, the inner end of the socket being formed with an in weirdly extending flange 17 to restrict move- Inentof the lamp 16 within its socket member and prevent the lamp from moving the.

contact member to an inactive position, upon the lnsert on of alamp.

Positioned within thesocket member 14 is a tubular housing 18 which supports the contact block. 19 that carries the contact member 2O,fprm1ng an important feature of'the invention. This contact member. is

formed preferably of a strip of flexible metal 'haying an-opening 21 and a contact head 22, 1t be1ng understood that the length of metal is bent intermediate its ends to bring the'endsthereof topositions in spaced relation with each other. The opening formed in one end of the contact member is designed to accommodate the securing screw 23, whereby the contact block may act as the support for the contact members 20. Thus it will beseen that the opposite end of the contact member 'lies in a position to be engaged by the contact member ofthe lamp bulb positioned in thei ocket.

A' cover indicated at 24 forms a part of the lamp housing and is formed with a threaded portion to be received by the threaded, portion 9 of the lamp casing, whereby the cover may be removably secured. to the lamp housing. The cover is ormed withsuitable'letters or numbers, by cutting away portions of the ccw'erv as shown d by Figure 2' of the drawings. Positioned at the rear of the cover is a transparent member 25 suitably colored to indicate anger. The lamp may be in circuit with any suitable source of electric supply." and may be controlled by a suitable switch member, not

. Having thus described the invention, what is claimed as new is 1. A signaling lamp including a body portion having a rearwardly extending portion Patented Apr. is, was.

clearly shown by Figure 1 of the rec provided with a flange, an insulating collar contacting with the flange, a socket member threaded within the rearwardly extending portion and contacting with the socket memher to secure the insulating collar against mevemen't', a socket forming a part of the a socket member, e contnct'bloclz positioned Within-the socket member and carrying a wet member,

said Contact member being for led or s 59 e3 flexible material bent 11 0.71 itself, lamp positioned within the secret member adapted to engage the Contact member, and a cover for the body portion.

A signaling lamp including a-bocly'bortion having a reerwardlyex'tending portion provided with flange, in insulating collar engaging the flange, :1 socket member positioned within the reerwar'dly extending por-' tien. and contectin with the insulatin colblar, a socket forming a part of the socket member and having an inwardly extending flange, a lamp positioned within the socket and adapted to engage the inwardly extending flange of the socket to restrict movement thereof, means within the'socket" member for
